Three-dimensional Reconstruction Research on the Anatomic Structure of Fengfu Acupoint

Objective: On the basis of displaying sectional images, reconstruction and cutting of the human body were done using a three dimensional (3D) reconstruction software in computer for revealing the anatomic structure of Fengfu (GV 16) from different layers. Methods: A formalin fixed male corpse (2 years) was used in this study. ABS fluid mixed with scarlet dye was used for arterial perfusion to display large blood vessels. After locating Fengfu (GV 16) according to the national standards of acupoints and freezing the body (-30 ℃), a hole was made along GV 16 to the routinely used depth using a high speed bit, and then filled with red plasticine for displaying different cross sections of the acupoint. The frozen sample was then put into a wooden box which was filled with water to be frozen again, and was cut into less than 2 mm thick sections with a high speed steel plane machine, photographed and videotaped. The collected images were fed into a computer and reconstructed into facade and dorsal pictures with 3D reconstruction software, on the basis of which, sagittal, coronal and horizontal plane cutting of the body were carried out. Results: 200 pieces of reconstructed pictures of Fengfu (GV 16) were obtained. From the reconstructed sagittal plane and coronal plane images of GV 16 the blood vessels, muscular tissues, etc. could be seen distinctly. Additionally, other structures were also shown clearly. For example, the sagittal pictures of Fengfu (GV 16) distinctly displayed the appearance of the brain, cerebellum and the spinal cord. On the coronal plane, the images of GV 16 showed the fascia and muscle tissues. From the horizontal plane images, the appearance of the bottom of the cerebellar hemisphere, medulla oblongata, the head semispinal muscle, etc could be seen. Images of the oblique plane, the head splenius muscle (on one side of GV 16) and the head semispinal muscle (deep layer) could be seen. Conclusion: The reconstructed pictures of Fengfu (GV 16) from the entity images with the software show the clear structures, which has the bright color and satisfactory resolving power.
